3.10 Reinstalling Differential and Axles
F Undo the retaining pin on the long cross shaft, and remove the long
cross shaft, spider block and thrust block from the Air Locker.
F Replace the paper gasket on the axle housing flange.
F Reinstall the third member to the differential housing according to
the vehicle service manual.
F Replace the axle seals if necessary.
F Rotate the differential until the access window in the Air Locker is in
view and accessible.
F Insert both axles fully into the housing, engaging splines, and then
gently tap them inwards.
NOTE : Be careful not to damage the axle shaft oil seals when
installing the axle. Support the axle’s entire weight
where possible.
F Select the two 2.8mm [0.110”] C-clips from the C-clip kit supplied
with your Air Locker and install them onto the axles.
NOTE : Your kit comes with 8 clips of 4 different sizes,
2.80mm [0.110”], 3.00mm [0.118”], 3.40mm [0.134”],
and 3.55mm [0.140”] and your original C-clips should
be 3.20mm [0.126”].
F Gently tap both axles outward until both C-clips are fully seated into
the side gears of the Air Locker.
F Insert the thrust block between the ends of the axles and hold it
against one axle.
F Using an automotive feeler gauge (take note as to whether your
feeler gauge is in Metric or Imperial), measure the remaining gap
between the thrust block and the other axle and record this
measurement as ‘A’.
F Calculate the thickness of the required C-clips using the equation
below that corresponds to your feeler gauge measurement:
METRIC : A ÷ 2 + 2.8
IMPERIAL : A ч 2 + 0.11
